    Technology of intelligent hotel lock

    In the course of development of intelligent lock, the most critical is the smart door locks unlocking technology, unlocking technique is done through automatic identification technology, mainly through barcode recognition, IC card, magnetic card recognition recognition, biometric identification of the development process.

    Barcode is the earliest right now are not used on above the lock, usually at the supermarket shopping, goods will be above a row of thick black line that is the bar code.

    First smart lock is the first widely used in magnetic card recognition technology. Electronic magnetic card lock key or magnetic stripe cards, magnetic stripe cards is based on liquid magnetic material or magnetic strip for information carriers, liquid coated with magnetic material on the card (such as books) or attach magnetic strips on cards (such as UnionPay cards). Because the information card is relatively simple and easy to read and write, easy to use, low cost and early access to development, and in many areas of application, such as banking, finance, post and telecommunications, communication, transportation, tourism, healthcare, education, hotel and so on. Magnetic card door locks are mainly concentrated in hotel establishments. Nowadays, magnetic card door locks in most hotel door locks have not adopted, only a small number of foreign hotel chains have seen its shadow.

    But because the magnetic cards can easily be copied, safety performance is low, then there is a IC card identification technology. Intelligent IC card lock, IC card is an integrated circuit card through card integrated circuits to store information from IC card security and memory chips are different and non-encrypted memory card (non-encrypted card or ID card), encrypt storage card (cryptographic card), a CPU card. non-encrypted memory card card EEPROM is the main IC chip, with data storage capabilities, without data processing capability and hardware encryption. encrypt storage card: non-encrypted memory card based on the encryption logic circuit, encryption logic circuit by checking a password to protect the access data to an external opening, but is a low level of security, to guard against malicious attacks. CPU card: also known as a smart card, this card is a microprocessor CPU, storage units, user data memory and chip operating system COS form integrated circuits. Such cards are equivalent to a microcomputer, can not only store data as well to commands and data protection.

    One step that safety of locks is to use biometric technology. Biometrics is the use of the inherent physiological characteristics to identify, mainly divided into voice-activated lock, fingerprint, iris recognition, hand geometry, vein recognition recognition, face recognition, and so on. Smart door locks biometric technologies applications, directly caused the smart door electronic key in updates. Most often we see is the fingerprint lock lock, fingerprint lock by identifying fingerprinting refers to we finger ends positively the jagged lines on the skin, these lines in varying patterns, breakpoints, and intersection. Unique and fingerprints can not only from Poria cocos Wolf the finger itself, can also be obtained from traces of suspect objects it touches. This characteristic of the fingerprint identification of the evidence most widely used in the field. Including fingerprint lock, fingerprint, fingerprint machines and other products, and is convenient, safe, fast, accurate and so on.

    Past ten years due to RFID (radio frequency identification) rise of the IC card lock combined with radio frequency identification technology, the development of non-contact IC card lock. By definition is not required to access, read and write operations done through radio waves. non-contact IC card can be divided into: RF encryption type (RF ID), commonly referred to as ID card. radio frequency card access to information is done through radio waves. No mechanical contact between the host and radio frequency, such as HID,INDARA,TI,EM and so on. Most schools use meal cards (of thickness), the card belongs to the ID card. RF card (RF IC) commonly referred to as non-contact IC card. Radio frequency card access information through radio. It is based on the memory card increases the RF Circuit. For example, MIFAREONE. Early bus cards used by some urban, some schools use meal cards, hot water, which belongs to the RF card. frequency CPU card (RF CPU) commonly referred to as active card is CPU card on the basis of the RF Circuit. Non-contact IC card locks, antifouling is not only waterproof, dustproof, and COS have their own operating system, called real smart cards. Big city bus card, financial IC cards, a handful of school meal card, belonging to the RF CPU card.

    Door locks development up to now has thousands of years of history, through a variety of changes necessary to become a family of products, and because of the use of science and technology, mechanical locks experts to evolve into intelligent locks, greatly improves the safety of the people, and privacy.
